The president’s approval rating is underwater in Iowa, Wisconsin and Michigan. Senator Joni Ernst, the Republican senator, has gone from being very popular to being the third most unpopular senator in the country, with an approval rating of just 37%, behind only Senator Susan Collins, of Maine, and the Senate majority leader, Mitch McConnell, of Kentucky, according to Morning Consult.
